Last month, Special Head’s levitation trick on America’s Got Talent created quite a buzz. Special Head was certainly not the first person to perform such a trick and he surely won’t be the last. Performance artist Johan Lorbeer did a slight variation of this stunt by casually leaning against the wall of a building while hovering over a large crowd of people. Can you figure out how he did it?

In the following video, he performs the same trick on the wall of a bookstore in Linz, Austria.
